Scheduling Mechanisms in Wireless Sensor-Actuator Networks for Multi-rate Periodic Control in Industry 4.0
arXiv:2605.30520v1 Announce Type: new Abstract: This paper investigates scheduling strategies for wireless sensor-actuator networks (WSANs) in Industry 4.0 scenarios. In particular, we address the problem of real-time scheduling for multi-rate control systems by proposing a novel framework.
Online Learning for Supervisory Switching Control
arXiv:2603.14762v3 Announce Type: replace-cross Abstract: We study supervisory switching control for partially-observed linear dynamical systems. The objective is to identify and deploy a suitable controller for the unknown system by periodically selecting among a collection of $N$ candidate controllers, some of which may destabilize the underlying system. While classical estimator-based supervisory control guarantees asymptotic stability, it lacks quantitative finite-time performance bounds.
REGEN: Reference-Guided Synthetic Multivariate Time Series Generation for Forecasting
arXiv:2606.05264v1 Announce Type: new Abstract: Training robust multivariate time series forecasting models requires large, diverse corpora, yet many real-world domains provide only a handful of observed sequences. Existing generators fail to resolve this mismatch: prior-based approaches (e.g., CauKer, TimePFN) produce domain-agnostic samples, while data-driven methods (e.g., TimeGAN) treat references as black-box supervision, forfeiting explicit control over periodic structure, local...
Picometer-Scale Spatial Symmetry Breaking in Active Transmissive Metasurfaces
Announce Type: replace Abstract: Active transmissive metasurfaces are central building blocks for future compact, cascadable optical systems, enabling the stacking of multiple functional layers for advanced dynamic beam shaping, photonic neural networks, depth sensing, and holography. We present a transmissive electro-optic metasurface based on silicon-on-lithium-niobate, where an array of silicon waveguides with periodic perturbations, individually controlled at the 100 pm scale, supports...
Near-axis quasi-isodynamic database
arXiv:2601.08400v3 Announce Type: replace Abstract: In this work, we investigate the landscape of quasi-isodynamic stellarators using the near-axis expansion of the magnetic field. Building on recent theoretical developments, we construct a database of more than 800,000 stable, approximately quasi-isodynamic vacuum magnetic configurations. These configurations span a range of field period numbers and other geometric control parameters, including the magnetic axis shape and plasma elongation.
GAPVD1 regulates CSNK1D-dependent PER2 FASP phosphorylation
The mammalian circadian clock relies on precisely timed transcriptional and post-translational events to generate ~24-hour rhythms. A key post-translational mechanism is phosphorylation of PER2 by CSNK1D, governed by a phosphoswitch that integrates stabilizing and destabilizing phosphorylation marks at the FASP and Degron sites to control PER2 stability and circadian period. Here, a novel role for the PER complex protein GAPVD1 in regulating CSNK1D-mediated FASP site phosphorylation is revealed.
From The Sports Desk: Carolina storms back to beat Vegas, even Stanley Cup Final
In Game 2 of the Stanley Cup Final, the Vegas Golden Knights held a 2-0 lead entering the third period and seemed poised to take control of this series. Then Carolina scored three unanswered goals and another in overtime to tie the series 1-1. Our Andrew Greif breaks it all down.
Two Degree-of-Freedom Vibratory Transport in a Grasp
Announce Type: new Abstract: In this paper, we use asymmetric vibrations to demonstrate two degree-of-freedom (DoF) in-hand manipulation of grasped parts. The asymmetric vibrations are achieved through closed-loop position control of a moving surface, which applies a periodic stick-slip waveform to the part to be manipulated. We show analytically how two vibratory waveform parameters, the sticking acceleration and the slipping acceleration, affect average part velocity when moving against...
Sharp periodic Ge concentration modulations beyond the conduction band valley wavevector $k_0$ in nuclear spin-free Si quantum wells
new Abstract: Periodic Ge modulations within strained Si quantum wells in SiGe heterostructures offer a route to deterministically enhance conduction-band valley splitting in Si, a key requirement for scalable spin-qubit quantum computing. Efficient enhancement requires modulations in the order of the Si valley wavevector $k_0$ (9.7 nm$^{-1}$), corresponding to a period of 0.64 nm and near-monolayer growth control. Using nuclear-spin-free molecular beam epitaxy with $^{28}$Si and $^{72}$Ge,...
Floquet Nonadiabatic Dynamics for Light-Matter Interactions: Recent Advances and Emerging Opportunities
Announce Type: new Abstract: Light-matter interactions provide versatile routes for probing and controlling chemical reactivity, charge transport, and material properties. Time-periodic external fields can reshape electronic states and open new dynamical pathways beyond the field-free Born-Oppenheimer (BO) picture. Floquet nonadiabatic dynamics has consequently emerged as an important framework for describing coupled electron-nuclear dynamics under periodic driving.
